Which formula calculates power consumption?

The formula for calculating power consumption is based on the relationship between volts, amps, and the time the power is used. The correct answer incorporates the basic principle of power, which is measured in watts.

In electrical systems, the power (in watts) can be calculated by multiplying voltage (in volts) by current (in amps). This gives you the total power consumption at any given moment. To understand power consumption over a specific period, such as 24 hours, you would need to multiply this instantaneous power by the duration of time in hours.

The key aspect of the correct formula is that it also includes division by 1000. This conversion is crucial because power consumption in kilowatts (kW) is often used in utility billing. The division by 1000 takes the total watt-hours (the product of volts, amps, and time in hours) and converts it into kilowatt-hours (kWh), which is the standard unit used for electricity billing and consumption reporting.

Thus, the formula effectively captures both the amount of power consumed (in kilowatts) over a specified time, allowing one to understand energy usage in a common format that relates directly to costs and efficiency. Understanding this relationship is critical in fields such as structural
